h) 2, where \(\lambda _{0}\ge 1\)  was chosen in Theorem 5.1. Choose the number \(\lambda _{1}\ge \lambda _{0}\)  depending on the parameters listed in (REF ) such that \(\widetilde{C}_{1}\lambda _{1}^{2}/2\ge C_{1}\)  and keep in
mind Remark 5.1. Then (REF ) implies () and ().
Given () and (), the existence and uniqueness of the
minimizer \(V_{\min ,\lambda }^{h}\in \overline{S^{h}\left( R,P^{h}\right) }\)  of the functional \(J_{\lambda }^{h}\left( V^{h}\right) \)  on the set \(\overline{S\left( R,P^{h}\right) }\)  for every \(\lambda \ge \lambda _{1}\)  as
well as inequality (REF ) follow immediately from a combination of
Lemma 2.1 and Theorem 2.1 of [1]}. \(\square \)
